Telecom sites / Technological environments
Were Emerson Network Power, backed by Emerson, a global com-
pany that brings technology and engineering together to provideinnovative solutions for the benefit of our customers.
Were the world leader in providing Business-Critical Continuity
to organizations like yours, enabled by our product and service cen-
tres of expertise.
For wireless telecom applications, we providecontrol of remote access node environmental
conditions. Our product portfolio includes a
wide range of configurable solutions; outdoor
packaged wall-mounting cooling system for
shelters, when theres not enough space avai-
lable inside the site; indoor packaged floor
standing cooling system, to remotely reject,
the heat generated by electronic equipment
from IT rooms inside buildings; split system,
to adapt the cooling solution to whatever site
position, dimension and layout.

Product overview
The Liebert HPF represents the most com-plete package indoor cooling system pro-duct family specifically designed to con-trol the environmental conditions intechnological or industrial rooms as wellas inside Fixed and Mobile TelecomNetwork sites.
The Liebert HPF units are designed forindoor and floor-mount application withover under or displacement air delivery.
In direct expansion mode the priority isgiven to the energy saving that is reached
through the attention given at design levelto all processes that realize the coolingeffect: high fan efficiency, perfect unitinsulation, performing heat exchange,smart logic control.
The use of direct free-cooling mode istuned to enhance the respect of the envi-ronment trough the setting of the controlthat aim to minimize the waste of energyin every condition.
The possibility to switch in emergencycooling mode, through the use of 48VDCor 230VAC plug fan, assure the continuityof protection from the risk of working inimproper climatic conditions

Providing the needed qualityto the cooling effect
Protecting the site from the attacks of the exter-nal environment its not a game.Liebert HPF cleans the air trough an efficient filte-ring system easy to be serviced and maintained;Liebert HPF cools the air through the lowest ener-gy consumption thanks to the use of high classcomponents; Liebert HPF avoids the waste of theobtained cooling effect through the high care ofthe unit panels insulation.
Riding any critical conditions
When the external temperature rises to the unex-pected temperature, when the environment
hazard the air filtering system, when the indoor
temperature, for any reason creates the hot startcondition, the cooling system cant abandon yourapplication. The availability of high ESP fan meanscapacity to react to the unwilled situation thatcould jeopardize your business.
Continuity of revenue from the site
Liebert HPF can be powered by 48VDC emergen-cy power source in case of mains failure.Continued ventilation and the maximized free-cooling mode assure constant operation of thetelecommunications equipment. The 230V ACemergency supply is also available for applica-tions offering the assistance of UPS or AC genera-
tor systems.

Always delivering cooling to its target
The delivery of the treated air is fundamental to
cool the site with efficiency and effectiveness.
Cooled air must be supplied where it is needed:
depending from the site layout the application
could require the air distribution from grilles
through a false floor, from top ducts or through
the ceiling, directly at floor level to cool the elec-
tronic equipment. This is exactly what Liebert HPF
is asked to do and does in the under, the over and
the displacement version.
Suitable to critical indoor installations
Technological environmnets inside historical buil-
dings as well as telecom sites in high rise buildings
are often located in sites where the supply of theexternal air is critical and it is not allowed to install
external units. The heart of the communication
needs a cooling system for indoor application
able to guarantee the most effective air intake
system through the use of high ESP fans, self
adapting to the pressure drops of the site ducting,
in order to provide efficiency of the cooling cycle
when working in direct expansion and highest
energy saving when working in free-cooling
mode.
Providing freedom of site layout at the design stage
The use of an indoor package cooling systemcant prevent from letting the right space andposition to the electronic rack. At this purposeLiebert HPF gives the possibility of being installedwherever it is allowed: in the middle of the roomwith rear connection to the remote wall or in a
corner with lateral connection directly to the sideof the building. The Liebert HPF compactness andconfigurability dont limit the user freedom ofdrawing the most suitable site layout.

Easy of installation and fast start up
The cooling circuit is pre-charged, fine tuned andfully tested before the delivery. No pressure test isrequired on site. Installation is furthermore spee-ded up by using the fast plug electrical connec-tions (on request) and the automatic commissio-ning software: installation and commissioning are
completed in less than 25 mins. without need ofspecialized personnel on site.
Generating high energy saving withcooling lifetime extension
A close control cooling system is required to work24 hours a day, 365 days a year: the must is tominimize the demand of energy supply in order tobe cheaper to run and to prevent the impact onclimate change. Liebert HPF aims to maximize the
energy saving without compromising its effecti-veness. The EC fan version reduces by 30% theenergy consumption of the evaporating fan, com-pared to the traditional AC fan motors. To the
results obtained with its high cooling efficiency,Liebert HPF adds the savings guaranteed by thefree-cooling mode and maximized through theuse of modulating fans either AC or DC supplied;when the fresh air is available the compressor andthe condenser fan stop as well as the evaporatorfan limits its speed in order to adapt the cooling
capacity to the application heat load, with highestenergy saving when working at partial loads con-ditions. As consequence the lifetime of the coo-ling unit is extended with delay of its replacementtime.
Facilitating the service
Liebert HPF guarantees easy and speed of accessto all main components during the ordinary main-tenance increasing the effectiveness of the servi-
ce action worked out in perfect safety conditions.The need of extraordinary maintenance is redu-ced to a minimum thanks to the quality of thecomponents selected at the design level.
